Your outline
I. Introduction
A. Hook: Most teenagers arrive at their first class still biologically asleep.
B. Thesis: High schools should move start times to 8:30 a.m. or later because it improves student health and raises academic performance.
II. Body Paragraph 1
A. Topic sentence: Later start times align the school day with adolescent sleep biology.
1. Teen circadian rhythms shift later during puberty
2. Most teenagers need 8–10 hours of sleep each night
III. Body Paragraph 2
A. Topic sentence: Well-rested students perform better academically.
1. Attention, memory, and mood improve with adequate sleep
2. Districts report higher grades after delaying the first bell
IV. Body Paragraph 3
A. Topic sentence: Later starts reduce health and safety risks.
1. Fewer drowsy-driving crashes among teen drivers
2. Lower reported rates of anxiety and depression
V. Conclusion
A. Restate thesis: Delaying the first bell is a low-cost change that supports healthier, higher-achieving students.
B. Closing thought: a final insight, implication, or call to action

Copy the plain-text version straight into your document, then expand each point into full sentences as you draft.

An essay outline arranges your thesis and supporting points into standard I / A / 1 notation. Enter a thesis, an optional hook, and two to five body paragraphs with their topic sentences and evidence. A classic five-paragraph essay has three body paragraphs, giving five sections: an introduction, three body paragraphs, and a conclusion.

What a good outline contains

An outline is the skeleton of your essay: it fixes the order of your ideas before you write full sentences, so you can see whether the argument flows and every paragraph earns its place. Each body paragraph opens with a topic sentence — a mini-claim that supports the thesis — followed by the evidence and reasoning that back it up.

The five-paragraph essay is the standard template: an introduction ending in the thesis, three body paragraphs, and a conclusion. It is a starting point, not a ceiling. Longer assignments simply add body paragraphs — a research paper might run to eight or ten — while the same nesting (section → key idea → evidence → detail) holds at any length. This builder lets you set two to five body paragraphs and keeps the notation consistent as you go.

  1. 1
    State your thesis. Write the one-sentence claim your essay defends; it anchors section I as the last line of the introduction.
  2. 2
    Choose your body paragraphs. Pick two to five, one per main reason. Three is the classic five-paragraph structure.
  3. 3
    Add a topic sentence for each. Each body paragraph gets one mini-claim (level A) that clearly supports the thesis.
  4. 4
    List the evidence. Under each topic sentence, add supporting points one per line — they become the numbered items (level 1).
  5. 5
    Restate and copy. Write a concluding restatement, then copy the indented outline straight into your document to start drafting.

Standard outline notation

Alternate between numbers and letters as you go deeper; indent each level once.

Common outlining mistakes

Topic sentences that only name a subject. “Sleep” is a topic, not a topic sentence; “Later start times align the school day with teen sleep biology” makes a claim the paragraph can prove.

Body paragraphs that do not point back to the thesis. If a paragraph does not advance the claim in section I, cut it or rewrite the thesis. Every section should trace back to that one sentence.

Treating the outline as final. An outline is a plan you will revise. Move paragraphs, split overloaded points, and merge thin ones freely — it is far cheaper to reorder here than after a full draft.

What is the five-paragraph essay structure?
An introduction that ends with the thesis, three body paragraphs each developing one supporting point, and a conclusion that restates the thesis and closes the argument — five sections in total.
How many body paragraphs should I have?
Use one body paragraph per main reason. Three is the classic five-paragraph structure, but two to five is common; longer research papers may run to eight or more.
What is the difference between a topic sentence and the thesis?
The thesis is the single claim the whole essay defends; a topic sentence is a smaller claim that opens one body paragraph and supports the thesis.
What does the I / A / 1 / a notation mean?
It marks the outline’s levels: Roman numerals for main sections, capital letters for key ideas, numbers for evidence, and lowercase letters for finer detail — each level indented once further.
How does the copy button format the outline?
It copies clean plain text with four-space indentation per level and your title on top, so it pastes into Google Docs or Word with the structure intact.
How do I turn one supporting point into two lines?
Put each point on its own line in the supporting-points box; every non-empty line becomes a separate numbered item, and blank lines are ignored.
Where does the thesis go in the outline?
At the end of the introduction (section I). It is the last thing the reader sees before the first body paragraph, so it frames everything that follows.
